Hanukkah starts at sunset on the 20th.

Relevance?

Hanukkah is around the same time as Christmas, but it is not nearly as important a holiday. Jewish voters are not going to stop paying attention to politics on Hannukah the way Christian voters will on Christmas and New Years.

I suppose some candidate could gain some minor support with a tasteful event at a Des Moines or Manchester synagogue. But no one expects or insists on it.
